WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 254,086, dated February 21, 1882.

' Application filed July 2, 1881. (Model.)

To all whom it may concern:

Be it known that I, ALEXANDER G. ALEX- ANDER, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Water-Closets, of which the following is a specification.

In the drawings, Figure 1 is -a vertical section of my improved water-closet, looking from the rear. Fig. 2 is a top plan view. Fig. 3 is a section on line 00 :10, Fig. 1'. Fig. 4 is a sectional view of the valve; Fig. 5, a detached view of the lower portion of the metal bowl broken away to show the bevel on the valveseat.

- The principle of this closet is the same as that of the closet patented to me the 30th November, 1880, (Patent No.234,934,) there being some changes in details of construction.

My invention consists in making a waterwaybetween the iron and porcelain bowls,from the bottom of the tank to the bottom of the iron bowl, so that when the escape-valve is opened a portion of the water in the tank will be discharged on the valve in the axial line of the arm which carries the valve.

A is a porcelain bowl, which may be of any desired shape.

B is a metal bowl, into which bowl A fits and is cemented. One side of the bowl B is cast so as to form three sides of a tank, B, the fourth side being formed by the bowl A.

G is a hole or slot in bowl A, giving free communication between tank B and bowl A. Slot G should be placed at or close to the bottom of tank B.

The lower end of bowl B is provided with a flange, T, by means of which it is bolted to a .metal trunk, D.

It is a valve-seat-,made of any suitable metal,

having a flange all around its upper part, and is held in position between flange T and the upper part of trunk D, a ring of suitable packing being laid on the flange of valve-seat R to make a gas or water tight joint.

F is a valve, consisting of a metal disk having a rubber disk, 0, thereon, and above said rubber disk a porcelain or metal washer, P, all

parts of said valve being connected by a screwbolt, as shown in Fig. 1. Valve F is set on the end of an arm fastened to rock-shaft E, and is held firmly pressed against its seat R by weight W, also fastened to rockshaft E. S is a pull for opening the valve F.

L is a valve for regulating the admission of water to the bowl A.-

N is the service-pipe, leading from the source of water-supply into valve L, and M is the delivery-pipe, leading from valve L to the bowl A.

O is a hollow ball or float fastened to the long arm of a crank, K.

K is a crank fastened atits center on a pivot, and having its arms of unequal length, the float 0 being fastened to the long arm, and the end of the short arm engaging with the piston U of the valve L. At the end of the short arm of crank K a small wheel is pivoted, as shown in Fig. 4 to reduce friction.

U is a valved stem having a slot in one end to receive the short arm of crank K, and provided at its other end with a washer of suitable material, so that when the piston is forced against the inner end of delivery-pipe M a water-tight joint will be made. It will be noticed that the diameter of valved stem U is practically the same as the diameter of the bore of pipe M, and this prevents a heavy waterpressure from holding valved stem Uso tightly against pipe M that the weight of float G will 7 not open valve L when the water falls in tank B-a common source of annoyance in watercloset valves which open against the pressure of the water-supply.

I is an overflow for tank B and-bowl A, having a trap therein.

H is a water way or passage cast in bowl B, running from the bottom of tank B to the lower edge of bowls A and B, and terminating in a beveled way out partially through the flange on valve-seat It, as more clearly shown at a in Fig. 5. The lower end of passage H is directly above the arm which carries valve F viz., in the front of the lower opening of bowl B. When valve F is opened the beveled portion or bottom of passage H gives the stream of water issuin g therefrom an inclination across the upper face of valve F, thus tending to sweep away from said valve and the arm which carries it anypaper or other obstruction which might otherwise lodge on said Valve or arm.

The operation of my improved water-closet 5 is the same as that described in my previous patent hereinbefore mentioned. What I claim as myinvention, and desire to secure by Letters Patent, is-

In a-water-eloset, thecombinntion of the bowl A, bowl 13, having the passage H cast therein, 10 and valve-seat R, the upper portion thereof being beveled to deflect the stream of water passing through passage H, as and for the purposes described.
